s air pollution. The area around Taichung City is very mountainous and interrupts the smooth flow of air. This is worse in the winter months when pollution can hang in the air for days. Past experience has shown that the haze is prone to occur after the beginning of autumn. Because of ...
The various routes of uptake are the nasal microvasculature, the olfactory epithelium, the microvasculature of the lung alveoli, and the GIT via the oropharynx (Table 1 and Figure 1), discussed in detail in the following sections, including how they can relate to the uptake of aeronutrients. ...
Airflow in the lungs results from an imposed pressure difference between the mouth and the alveoli, both for inspiration and expiration. The airways conducting the flow are a branching network of tubes which makes the relationship between pressure and flow complicated. This article covers the basic...

Inhalability (I) refers to the intake efficiency of ambient particles to enter the mouth and nose of a human subject. This efficiency depends on both air flow close to the subject and the particle size. Different analytical equations have been proposed in the scientific literature for the defin...
massmof the mammal but also to its maximal running speedv. More precisely, the results allow establishing a scaling law relating the efficiency of air conditioning in the nose of mammals to the ratio. The simulations also correlate the resistance to the flow in the nose to the efficiency of ...
Accu-Sample™ control completely isolates samples within specific, low-volume flow path segments, and prevents trap exposure during important sample select and preflush operations. The 7200’s built-in loop option allows as little as 0.25cc to be precisely controlled and injected. The result is ...
Physiologic Dead space: This is when there is well ventilated alveoli, but there is no blood flow. This can affect ventilation and perfusion ratios. Answer and Explanation: Answer: Ventilation:Perfusion Ratio is matching airflow to blood flow in the lungs. Ventilation Perfusion Rati...
